This describes Tesla's development work on the TT.

Not GE. What today is called Con-Ed.

Not GE, again.

Allis Chalmers !
( I tell you, Tesla definitely needed a business manager ... )
A little research will show Tesla's diagrams online.
Yes, he intended to use multi-stage turbines. Because there's a
limit on how much force any given disk can take.
But if you can find ANY diagram that shows a genuine TT with no hub
exhaust, I'd be happy to study it.
The reason I KNOW the hub exhaust was part of the original spec, is
that I studied the subject.
And one thing in particular sticks in my mind: ALL Tesla's turbine
designs were reversible.
Maybe a steam turbine would have a different shape injection nozzle,
or different runner spacing, but any turbine could work as a pump
without any alteration.
In a Tesla pump, water, for example, enters at the hub port and gets
spun up. In this case, the flip side of the turbine, the working
fluid gets accelerated and flung outward, something that does NOT
happen with the turbine.
The pressure at the rim is the same, though, and the working fluid
blows out the rim port at pressure.
